LOADING AND unnoannvs APPARATUS.

To all whom it may concern:

Be it known that I, LEWIS M. ODEN, a citizen of the United States, residing at Raleigh, in the county of Wake and State of North Carolina, have invented certain new and useful Improvements in Loading and Unloading Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the inventiomsuch as will enable others skilled in the art to which it appertains to make and use the same. I

The primary obj ect of this invention is to provide an extremely simple, practical and durable loading and unloading apparatus for use in connection with excavating scoops.

Another and more specific'object of the invention is to provide an apparatus of this type having an inclined base or platform, scoop supporting bars connected at the upper end of the platform and a head post or frame to which the bars are pivotally con nected by a tongue, whereby the platform and supporting bars may be swung in anarc without moving the headpiece.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in cer tain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the fol lowing description and accompanying drawings, in which,

Figure 1 is a perspective view of my loading and unloading apparatus, Fig. '2'is a fragmentary side elevation partly in section, showing the head frame and tongue pivotally connected thereto, Fig. 3 is a side elevation partly in section of the tail post, and parts connected thereto, Fig. dis a detail perspective view showing the socket to which the tongue is connected, Fig. 5 .is a detail view, showing one form of pulley or sheave forming part of my apparatus, and Fig. 6 is a detail perspective view of an axle and lubricator therefor, such as is used for they sheave. v

' Referring in detail to the drawings by numerals, 1 designates, asan entirety, a sup porting frame, which includes a base piece 2, a post or upright 3 and braces 4 and. 5. The braces 4 are connected at their lower ends to the base piece 2 adjacent the extremities thereof and converge upwardly Specification of Letters Patent.

forwardly from the post 3 and connects with 1 a crosspiece 6 which might be termed a secondary base. The bases 2 and 6 extend transversely of and are fastened upon frames 7 extendingfronia hoisting engine, not shown, having drums 8 and 9. The post 3 is formed with a 'recessor mortise 10 in which is journaled a pulley 11. The pulley revolves around an axle 12, such as shown in F 1g. 6, said axle being formed with a l0n-' gitudinal bore 13 opening upon one end thereof and extending to the center of the axle and then opening upon theupper face thereof. An oiling tube 14 'is threaded into the outer end of the bore13 and extendsupwardly along one side of th post3to which it is connected byastaple 15, or any other suitable means, such as is 'clearlyshownin Fig. 1. Oil may be introduced into the up U per end of the pipe 14 sothat the pulley will always be properly lubricated. This form of selfeoiling axle is employedin connection with each of the pulleys or sheaves to be I hereinafter mentioned. A lie or brace rod,

formed in sections 16 and 17 the opposed ends ofwhich are connected by a turnbuckle 18, extends along the outer face of the brace 5. The lower end of the section 16 is extended downwardly through the brace and base; or crosspiece 6 and has a nut threaded upon its, extremity. The upper endofthe section 17' is extended rearwardly through the brace 5 and post3, as best shown in Fig.

2,-and passes through an ear 19'formed on the base piece 20 of a socket.. Thissocket is set inthe rearface of the post 3 and'is securely connected thereto by bolts, or other suitable fasteners, 21,

in addition to the rod 17.

22 indicates a post or upright connected to a horizontal basepiece 23 and carrying upon its upper end a crosspiece 24 which is braced by the downwardly inclined mem- An inclined base orplatform 26 extends downwardly and rearwardly from the crosspiece 24: into engagement with the ground. It will'be noted that the platform widens-as it approaches its lower end, A

pair of parallel bars 27' connected at their rear ends to the upperface of the crosspieoe 24, "meet the upper ends of the'side bars 28 of the platform and are connected at'their forward ends by crosspieces 29 and 30. A tongue 31 is connected to the central, per

tions of the crosspieces 29 and 30 and eX- tends forwardly beyond said crosspiece 29. A cap 32 is bolted, or otherwise secured, to the forward end of the tongue and carries a king bolt 33 which extends through the sleeve 34: of the socket. It will be noted upon reference to Fig. 2 that the cap 32 rests upon the top of the socket sleeve so that the tongue is firmly supported thereby. A floor or platform 35 is arranged between the bars 27 and extends forwardly from the crosspiece 2a. A roller 35 is journaled between the parallel bars 27 in advance of the forward edge of the platform 35 and in the same plane with this platform. The floor or platform 35 may be .made of any length desired, and the roller 35' is alwa s Jlaced -ustin advance .l

of the platform, so that a scoop as it passes from the platform moves over the roller 35 and dumps between the bars 27. By varying the length of the platform 35 and the position of the roller 35, the place where the dumping operation takes place may be varied, as will be clearly understood.

A tail post 36 is used in connection with my improved loading and unloading apparatus, and is firmly anchored at some dis tance from the platform 26 on the far side of the excavation. A pair of sheaves 37 and 38 are pivotally connected to the tail post by means of eye bolts 39 and each sheave is provided with a main roller 40 and a guide roller e1 between which a cable works. This cable runs over supporting pulleys 43 mounted upon a guywire or cable 4.4, through the mortise 10 over the roller 11 and is connected at one end to the drum 8 of the hoisting engine. The other end of the cable is connected to the drum 9 and fro m here the cable passes through a sheave t5 connected to the post 3. This sheave is formed by side plates 4:6 riveted together and having journaled between them a roller or pulley 47 having a lubricating axle, such as illustrated in Fig. 6. The upper ends of the plates 46 are formed with registering openings L8 to receive the eye of an eyebolt 49. This bolt extends transversely through the post 3 and allows a swinging movement of the sheave. The guywire 4A is connected at one end near the top of the I tail post 36, passes over the topof the post- 3 and is connected at its other end to one of the frames 7, as shown in Fig. 1. i To prevent weathering, the top of the post 3 is protected by a cap 50.

Having described the construction of my loading and unloading apparatus, I will now proceed to a brief description of the operation thereof: An excavating scoop, not shown, is connected by a lead to the lead of the cable 42 and when the cable is wound onthe drum 9, the scoop will be drawn from the excavation up the inclined platform 26, over the roller 35 and will dump between the parallel bars 27. The scoop used is preferably of that type shown in my Patent No. 9923,8641 having side trunnions which-engage the bar 27 and pivotally supports the scoop as it swings between said bars to discharge its contents. After the scoop has been dumped the direction of movement of the cable is reversed and the scoop is drawn bacl; over the roller 35 and down the inclined platform 26. One serious difliculty heretofore found with apparatus of this type arose from the frequent necessity of shifting the positions of the platform 23 so that it properly faces the excavation.

, It-has been customary to have the platform and dumping bars rigidly connected to thehead post or frame 3 so that each time the platform was shifted, the head frame must necessarily shift also, which in turn required a movement of the engine. Now to overcome this difliculty I pivotally connect the tongue 31 to the post 3, as before mentioned, so that I may shift the position of the platform and pivot bars 27 without, disturbing the head frame or engine. This shift may, if desired, be affected, or at least assisted, by connecting the lower lead of the cable 42 to one lower corner of the platform 26 and running the cable over a pulley 51 anchored in a suitable position, as shown in Fig. 1. Upon reference to this figure it will be seen that when the cable is thus connected and wound upon tne drum 9, the platform will tend to swing in an arc. If it is desired to swing the platform in an opposite direction from that indicated in Fig. 1, the sheave or pulley 45 is transferred to the opposite side of the post 3 by removing the eye-bolt 4-9 and inserting it from the opposite side.

From the foregoing description taken in connection with the accompanying drawings, it will be apparent that I have provided a very simple, practical and highly efficient loading and unloading apparatus, which may be quickly and easily adjusted to accommodate a new position of operation of'the excavating scoop.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement 4 a iis its

tive to the head post.
